To all whom it may concern:

Be it known that 1, JAMES I". SALLows, a

citizen of the United States, residin at I Lansing, in the county of Ingham and tate of Michigan, have invented certain new and useful Improvements in Cable Grips, of which the followinr is e specification.

M invention retlates to cable grips, and its o ject is to furnish a device that shall be strong and reliable in operation, and yet simple and cheap in construction.

In the drawings, Figure 1 shows a longiform of my device,

tudinal elevation of one a part of the wall being broken away to show the arrangement of the gripping ribs. Fig. 2 a cross-elevation; Fig'. 3 is e crosssection of e modified construction; and Fig. -l is a plan view of the u per member of the same. Fig. shows a p an view' of 'a n1uditication of my device adapted to gripping a plurality of cables at one time.

My device is composed of two members; a drawin member, 1, and a gripping member, 2. As refer to construct it, the drawing member is provided on each side with a Harige or projection, 3, each of said flanges being adapted to slide in a corres ondmg groove in the gripping member, as s lown in Fig. 2; but it is evident that the relative positions of the flange epd groove might be reversed without departing from my invention. A tapering cable groove, 5, which may he either triangular, polygonal, or circular in cross-section is formed in each of the members. as shown in Figs. 2, 3, and 4, the two members being so pnt together that the smaller end of the groove in one is next to the largo end in tbe. other. lf it is desired to grip a plurality of cables, or wires at onetime. u plurality of grooves may be formed in thc two members, as shown in Fig. 5. The groove in the gripping member is iroferably, though not nexessarily, pro- "1 vh cd with ribs, G, rojecting slightly into bein n'ovicled P gl a grip ning the more tightly sitons shown by t.

The operation of the device is as follows: Suppose a cable be inserted in the device and a tractive force be ap lied to the drawing member, 1. The first e ect will be to slide the drawing member in the groove, 4, until it occupies the position shown by the dotted lines in Fig. l. On account of the tapering form of the rooves, 5, it is evident that, as they moved a on they would ip the cable more closely an( that the harerer the strain the cable would be gripped. Itis also evident that the gri can be readily released by movin the mem ers -into the poe dotted lines in Fig. 1, or b slidin them entirely apart, which can rea ily be one.

I claim as my invention and desire to secure by Letters Patent:

1. In a cable grip, a drawing member and a grip )ing member, slidablv connected to each ot 1er, each of said members bein provided with a tapering cable groove, su .antially as described.

2. In a cable grip, a drawing member and a gripping member, slidabl connected to cach other, each of said mem ers being provided with a taperin cable groove, the taper in said groove exten ing in relatively o posite directions, substantially as descri 3. ln a cable grip, a drawing member and member, slidabl connected to f each ot 1er, each of said mem )ers being provided with a tapering cable groove, the taper in said groove extending in relatively opposite directions, said Groove in one of said members being provided with gripping ribs, substantially as described.

4. In a cable grip, a drawing member and a frippimir member, slidably connected to cach other, cach of said members being provided with a tapering cable groove, the taper in said groove extcndinf in relatively op )ositc direction.' and said drawing mem cr with an extension adapted to connect with means for drawing, substan- The tially as described.
